16.6.5 Reception errors
reception result error flag is set in the UAnSTR register and a reception complete interrupt request signal (INTUAnR)
is output when an error occurs.
570
Three types of errors can occur during reception: parity errors, framing errors, and overrun errors. The data
It is possible to ascertain which error occurred during reception by reading the contents of the UAnSTR register.
Clear the reception error flag by writing 0 to it after reading it.
Caution When the INTUAnR signal is generated, the UAnSTR register must be read to check for
errors.
